Wavefront refractions and high order aberration correction when wavefront maps involve geometrical transformations

摘要

Wavefront measurements of eyes are typically taken when the pupil is in a firstconfiguration in an evaluation context. The results can be represented by a setof basis function coefficients. Prescriptive treatments are often appliedin a treatment context, which is different from the evaluation context. Hence,the patient pupil can be in a different, second configuration, during treatment.Systems and methods are provided for determining a transformed set of basis functioncoefficients, based on a difference between the first and second configurations,which can be used to establish the vision treatment.
